Extraction of chlorine from brine solution is based on

The electrolytic decomposition of dilute sulphuric acid with $Pt$ electrodes in the cathodic reaction is:

During electrolysis of water,the volume of $O_2$ liberated is $2.24 \ dm^3$. The volume of hydrogen liberated,under same conditions,will be .............. $dm^3$.

Give the reaction that occurs near the anode during the electrolysis of sulfuric acid in an electrolytic cell using an inert electrode.

The number of electrons passing per second through a cross-section of copper wire carrying $10^{-6} \ A$ of current is found to be:

How many moles of electrons are required for the reduction of $3 \ mol$ of ions of $Zn^{2+}$ to $Zn_{(s)}$?
